ssh sessions getting "paused" on idle - FreeBSD

Hi Guys, hopefully this is a stoopid question with an easy answer. I ssh to anything over 10 machines at a time and leave the xterms idle. When I come back to a session and press enter / start typing, it takes a few seconds to come alive. Almost as if the connection got canned. Do you think this could be ipfw related? Or is it a switch that i have to specify somewhere? As always, any help will be much appreciated.

    Default ssh sessions getting "paused" on idle

    Hi Guys,

    hopefully this is a stoopid question with an easy answer.

    I ssh to anything over 10 machines at a time and leave the xterms idle.
    When I come back to a session and press enter / start typing, it takes a
    few seconds to come alive. Almost as if the connection got canned.

    Do you think this could be ipfw related? Or is it a switch that i have
    to specify somewhere?

    As always, any help will be much appreciated.

    Thanks

    i can only tell you that when i'm using a not so good
    internet-connection my ssh-sessions suffer from that in a similar way as
    you described here, some people told me that ssh can be given highest
    priority with a traffic shaper (i think ipfw can do that too), that
    could solve this problem

    Thanks for the answer, I doubt that is the problem though. As I have at
    least 3MB links to all these servers (it's on throttled ethernet in our
    data centre ;)

    Well, it could be anything from a delay because the ssh processes are
    idle and have been swapped out to network delays. Does your disk
    become active when you resume an idle session, or are you simply seeing
    a 1-2 second delay as the network traffic gets exchanged and the
    session becomes active?
